Fixing a shiny black plastic handle with gorilla-brand superglue,
I made a sloppy mess of it. It leaked out of the joint and over the
surface.
Is there a solvent that will not destroy the plastic but will remove
that haze?
Or must I just reduce the haze with some other solvent or glaze to at
least
make it bumpy, but as shiny as before? Or at least shinier than it is
ow

Any ideas?

TIA!!

That depends on the type of glue. Is it a kind of Ethyl Cyanoacrylate
glue? http://www.gorillaglue.com/information/MSDS.aspx

Than you could have a chance using a mixture of Acetone/Propylene
Carbonate (it depends on the type of plastic).

Or a comercial cleaner like: 3M Scotch weld debonder/cleaner AC 68

You may have to use a Dremel and sand it down then add a shellac and
buff with fine sand paper

I have repaired this.

Remove everything from the area being worked on so you do not have any
obstructions.

Scrape off the big stuff with a NEW razor blade, (gently because any
scratches you make will have to be sanded out later.) Then start with
some 600-800 sandpaper. see if it gets out all the scratches you made
while scraping it off and that all of the glue is gone. If not, go
down a few grades to 400 or even 220 if needed. then work your way
back up once all the scratches are out. 800, 1000, 1500, 2000 and
then switch to rubbing compound and polishing compound and then finish
off with some of the Novus products for plastic.

You can shortcut this process by buying the "Headlight repair kits"
from and auto parts store. It will have all of the grits of sandpaper
you need, a tiny sanding pad for a drill and rubbing compund for under
$20.

When it is done it will look better than new.

Tip: if the area you are working on is too small for a full sized
razor blade you can use needle nose pliers and snap half of the razor
blade off and leave the part you hold intact.
